Abstract
A method for controlling the operation of an electronically commutated motor (ECM) is described. The method includes providing a pulse width modulated signal to an ECM controller and adjusting a duty cycle of the pulse width modulated signal to cause the ECM controller to regulate at least one of a maximum current drawn by the ECM and an average voltage applied to the ECM.
